Magnification

• What is magnification?

  Is the number of the times bigger an object appears when looking down a microscope
• What is resolution?

  Is the smallest measurement that can be made with a measuring instrument (such as a microscope). This is also called the resolving power of the microscope
• What is the equation for magnification?

  Magnification = size of image / actual size
• What is the equation for actual size?

  Actual size = image size / magnification
• What is the equation for image size?

  Image size = actual size x magnification
• What is the triangle formula for magnification?

  I

  A M

  I - image size

  A - actual size

  M - magnification
